OpenAI’s o1 and o3-mini are advanced reasoning models that differ from the base GPT-4 (often referred to as GPT-4o) in how they process prompts and produce answers. These models are designed to spend more time “thinking” through complex problems, mimicking a human’s analytical approach. To leverage these models effectively, it’s crucial to understand how to craft prompts that maximize their performance. In this article, I will be sharing some takeaways from OpenAI’s prompting guide!

Understanding Reasoning Models

OpenAI’s reasoning models, including o1 and o3-mini, are designed to tackle complex problems by emulating human-like analytical approaches. These models utilize reinforcement learning to enhance their reasoning capabilities, making them adept at subjects like mathematics, science, and coding. Unlike traditional GPT models, reasoning models spend additional time “thinking” through problems, generating detailed chains of thought before arriving at a conclusion. This deliberate process enables them to handle intricate tasks with greater accuracy and depth.

Managing Long Conversations and Memory Limits

Imagine you’re having a conversation with a really smart AI that remembers what you say. But, just like a notebook with limited pages, it can only remember a certain amount of information—128,000 words (tokens) worth.

  • First Turn:
    • You ask a question (input).
    • The AI thinks about it (reasoning) and gives an answer (output).
  • Second Turn:
    • The AI remembers your last question and answer.
    • It uses that memory to respond better.
  • Third Turn & Beyond:
    • The AI keeps adding new messages while remembering past ones.
    • But since its memory is limited (128k tokens), older parts of the conversation might get cut off (truncated output).

Why Does This Matter?

  • The AI keeps track of your conversation, but older details might disappear if the chat gets too long.
  • If you’re having a long discussion, important info might get lost unless you remind the AI.

Think of it like a whiteboard – once it’s full, you have to erase old notes to make space for new ones!

6 Insights from OpenAI’s Prompting Guide

Based on the latest resources shared by OpenAI, here’s my insights into optimizeed Prompt Engineering!

Simplicity is Key

When engaging with reasoning models, it’s essential to keep prompts clear and straightforward. Overly complex or convoluted instructions can confuse the model and lead to suboptimal responses. By articulating queries in a simple and direct manner, users can facilitate better understanding and more accurate outputs from the AI.

o1’s reasoning capabilities enable our multi-agent platform Matrix to produce exhaustive, well-formatted, and detailed responses when processing complex documents. For example, o1 enabled Matrix to easily identify baskets available under the restricted payments capacity in a credit agreement, with a basic prompt. No former models are as performant. o1 yielded stronger results on 52% of complex prompts on dense Credit Agreements compared to other models.

Example of a Good Prompt:
“What are the three primary reasons why the Roman Empire fell?”

Example of a Bad Prompt:
“Explain in detail, in a long and structured response, the economic, social, political, and military reasons behind the fall of the Roman Empire in the most comprehensive way possible.”

Avoid Overloading with Instructions

Contrary to some traditional prompting techniques, OpenAI advises against instructing models to “think step by step” or to “explain their reasoning.” Such directives can inadvertently hinder the model’s performance. Instead, allowing the model to naturally generate its reasoning process often yields more coherent and accurate results.

Example of a Good Prompt:
“What is the derivative of x² + 3x – 5?”

Example of a Bad Prompt:
“Calculate the derivative of x² + 3x – 5, and explain every single step as if you were writing a textbook for a beginner with no prior math knowledge.”

Utilize Delimiters for Clarity

Incorporating delimiters, such as quotation marks or parentheses, can help structure inputs effectively. This practice delineates different parts of the prompt, reducing ambiguity and guiding the model to interpret and respond to each segment appropriately. Clear structuring ensures that the model processes the prompt as intended, leading to more precise outputs.

Example of a Good Prompt:
“Analyze the sentence: ‘The quick brown fox jumps over the lazy dog.’ What is the subject and what is the verb?”

Example of a Bad Prompt:
“Analyze this sentence: The quick brown fox jumps over the lazy dog. Identify the subject and verb but also explain why they function as they do within the sentence structure.”

Zero-Shot Prompting as a First Approach

OpenAI recommends starting with zero-shot prompting, where the model is given a task without any examples. Reasoning models often perform well under these conditions, providing accurate responses without the need for illustrative examples. If the initial output doesn’t meet expectations, incorporating a few examples (few-shot prompting) can help refine the model’s responses.

Example of a Good Prompt:
“Translate ‘I love learning’ into French.”

Example of a Bad Prompt:
“If I have the sentence ‘I love learning’ and I want to translate it into another language, can you show me how it would be translated into French?”

Be Mindful of Prompt Engineering Techniques

While prompt engineering can enhance model performance, certain techniques may not be beneficial for reasoning models. For instance, instructing the model to “think step by step” might not always yield the desired outcome and can sometimes degrade performance. It’s crucial to understand the specific behaviors of reasoning models and tailor prompting strategies accordingly.

Example of a Good Prompt:
“Solve: 12x + 5 = 41”

Example of a Bad Prompt:
“Let’s solve the equation 12x + 5 = 41. Please think step by step and explain each calculation in the simplest way possible, ensuring no step is skipped.”

Leverage Model Customizability

OpenAI’s updated Model Specification emphasizes the customizability of their models. Users are encouraged to experiment with different prompting strategies to find what works best for their specific use cases. This flexibility allows for a more tailored interaction, enabling the model to better align with user expectations and requirements.

Example of a Bad Prompt:
“Give me an overview of the 2023 IPCC climate report, explain its importance, why it matters, what the key points are, and why policymakers should care about it.”

End Note

By following these guidelines, users can effectively harness the power of OpenAI’s reasoning models to tackle complex problems and obtain accurate, well-structured solutions. Understanding the nuances of prompt engineering for o1 and o3-mini allows users to leverage their unique capabilities and achieve optimal results in various domains, from legal analysis to research and strategy
